Cooking hob with window, cooking appliance, and process for manufacturing the hob

Abstract

A cooking hob, or a ceramic hob, for a fixed or mobile cooking appliance, the hob including at least one cooking area and at least one control and/or information area, the control and/or information area being formed by a window separated from the cooking area by at least one joint made of synthetic material. The joint includes a mechanism for fixing a control and/or display screen under the window.

The invention claimed is: 
     
       1. A cooking hob for a fixed or mobile cooking appliance comprising:
 a base hob, or a ceramic base hob, including at least one cooking area and including at least one control and/or information area, the control and/or information area being formed by a window separated from the base hob by at least one joint made of synthetic material, 
 wherein the joint includes an accessory that extends under an inner surface of the base hob and/or under an inner surface of the window to fix a control and/or display screen under the window, the accessory including a rail including a first leg, a second leg parallel to the first leg, and a third leg connecting the first leg to the second leg such that the rail is formed in the shape of an H, the first leg of the rail being encapsulated entirely within the material of the joint and the second leg protrudes outside of the joint and directly contacts the control and/or display screen. 
 
     
     
       2. The cooking hob as claimed in  claim 1 , wherein an inner part of the joint, in vertical section, is in a form of a C or an L under the inner surface of the window. 
     
     
       3. The cooking hob as claimed in  claim 1 , wherein at least part, or all, of an outer surface of the window is not in a plane of an outer surface of the base hob. 
     
     
       4. The cooking hob as claimed in  claim 1 , wherein the joint includes a joint outer part extending above a joint central part and/or extending over an outer surface of the base hob and/or over an outer surface of the window. 
     
     
       5. A fixed or mobile cooking appliance comprising a cooking hob as claimed in  claim 1 . 
     
     
       6. A process for manufacturing a cooking hob as claimed in  claim 1 , comprising:
 arranging the base hob and the window in a mold which is then closed; and 
 injecting a synthetic material into a mold cavity to form the joint including the accessory that extends under the inner surface of the base hob and/or under the inner surface of the window to fix the control and/or display screen under the window, the accessory including the rail including the first leg, the second leg parallel to the first lea, and the third leg connecting the first lea to the second leg such that the rail is formed in the shape of an H, the first leg of the rail being encapsulated entirely within the material of the joint and the second leg protrudes outside of the joint and directly contacts the control and/or display screen. 
 
     
     
       7. A process for manufacturing a cooking hob as claimed in  claim 1 , comprising:
 preforming the joint that includes the accessory that extends under the inner surface of the base hob and/or under the inner surface of the window to fix the control and/or display screen under the window, the accessory including the rail including the first leg, the second leg parallel to the first leg, and the third leg connecting the first leg to the second leg such that the rail is formed in the shape of an H, the first leg of the rail being encapsulated entirely within the material of the joint and the second leg protrudes outside of the joint and directly contacts the control and/or display screen; and 
 bonding the joint to the base hob and/or to the window. 
 
     
     
       8. A process for manufacturing a cooking hob as claimed in  claim 1 , comprising:
 molding the joint that includes the accessory that extends under the inner surface of the base hob and/or under the inner surface of the window to fix the control and/or display screen under the window against the base hob or against the window, the accessory including the rail including the first leg, the second lea parallel to the first lea, and the third leg connecting the first leg to the second lea such that the rail is formed in the shape of an H, the first leg of the rail being encapsulated entirely within the material of the joint and the second leg protrudes outside of the joint and directly contacts the control and/or display screen, the window or respectively the base hob then being introduced into a groove of a frame formed by the joint when the joint is hot. 
 
     
     
       9. The cooking hob as claimed in  claim 1 , wherein the joint directly contacts a top surface of the control and/or display screen and the accessory directly contacts a bottom surface of the control and/or display screen.
